| Gypsy: Another clean finish could have been <25.Kg1> Bd5+ 26.Kxf1 (26.Qxg8 Qxg8+) Bxf7 27.exd8Q+ Kxd8 28.Bxf7 Rf8, 0:1. |

| Marius: if 22.QxQ,Rd8xRd1 and white must have another queen, right? |

 |
| PivotalAnorak: Yes, if 22 QxQ then 22... RxR and game over. |

| MoonlitKnight: If you saw this all the way to the finish, then congratulations, either you've cheated or you are a Ferocious Beast! :) |

| bob725: Not even close. I looked at rook x g2 and then pawn advance to e2. |

| drcdwil: I actually solved this one but it took from midnight(when it first posted) until 12:30. I kept looking for checks and it became clear. Where to put the bishop for the discovered check gave me some problems until I realized that the White bishop would take the checking rook. I was proud but tired afterwards. I neither cheated nor I am FB! Well maybe latently "a" FB! :) |

| Gypsy: Here is my "truth in advertizing" <MoonlitKnight>: I computed the 20...e2 21.Nxe7+ Qxe7 22.Qxe7 ... variation as that clearly had to work for the combination to succeed. Besides that, I collected key resourcess for Black, namely Rxd1, Bxg2+, exd1, exf1, and also Bg2-d5+ (if Kg1) and decided that Black was good for mixing things up. Had I already seen the underpromotion possibility exf1N+ at this stage, I would now be strutting around like our cat when it catches a mouse. I looked at the intermezos for White briefly; saw but underestimated the game 22.Rxd8+. I restarted my thinking after the 22.Rxd8 and worked things to the end (using the 25...Bd5+ line I gave above). But I already noted the earlier underpromotion comment by <hollowone>, so I do know if I would have thought of it. That is a type of idea I sometimes easily see and sometimes easily miss. I forgot to look at the clock so I can not realy report the time; somewhere in the 5-10 minutes range probably. Over all I feel I performed at about 80% of Ferby. |

| tpstar: Any improvements for White in the opening or middlegame to avoid Black rolling over him like this? Good game. |
|

| MoonlitKnight: As for my above comment, I don't want to discredit anyone who spent a lot of time trying to solve this problem. Personally, I saw e2, sensed that it would lead to improbably complicated tactics and gave up immediately. My main problem with these Sunday puzzles is that I'm always hung over! |

| Gypsy: <tpstar: Any improvements for White in the opening or middlegame ...> Strangely, this game appears to be unhooked from the Opening Explorer. From what I can extrapolate from the small number of games there, White maneuver 7.Bb3 e6 8.Be3 is timid and Black stands well afterwards. Perhaps the position is still about equal here (I personally prefer Black quite a bit after 10...Bc6), but the further attack by White, 11.Bxf6 12.f4 13.Qh5 etc is built on too soft a foundation -- against Steinitz principles. Thus it just opens up too many lines for black pieces; and those bishops, rooks, and mobile pawns soon spell the disaster. (Of course, to be fair, it looks easy only when somebody like Ljubojevich is in charge of Black.) |

| kevin86: Queen sac,underpromotion,great combination to capture one queen and head another one off at the pass! A game to write mother about-even if you have to use stamps-like the old days. |
|
| Aug-01-04 |
| MoonlitKnight: I hardly think Ljubo's mother is online even nowadays... |

| Benzol: Well, I did manage to pick 20...e2 but I couldn't follow the combination right through to it's end. |

| Gypsy: <Knight13: Checkmate huh?> The simplest here is to grab overwhelming material: 28.Qe1 Qxe1+ 29.Kxe1 Bxb3 30.axb3 Re8 0:1. |
|
Aug-01-04
 |
| Knight13: It's checkmate soon enough. Or win material. |
|
Aug-01-04
|
| Knight13: <Gypsy> You are right. |
|
| Aug-01-04 |
| MoonlitKnight: That's easy enough, but the position is a mate in 3, just check out crafty's line. |
|

|
| Gypsy: That is right <Moonlight>, but I can seldom resist this maxim of Tartakower (I think Tartakower): "What is better, to give a mate in N moves or to simpy take the queen? It's better to take the queen, of course; then the mate is easy!" :-)) (I am amased how often that actually turns out to be true in practice.) |

| patzer2: If 23. Re1, then 23...Rxg2! looks decisive. |

| lostemperor: 20...?
Of course if it was an ordinary game I would automatically look at 20...e2. But since it is chessgames.com sunday's difficult tactical excersize I came up with the following after about 13 minutes which also includes the queen sacrifice which happened in the game. The only problem is it doesn't add up:-(. <20... Rxg2??!! 21 Qxe7> (I rejected 21.Kxg2! since it looks dangerous for white after 21... Rxd5, but this must be the refutation of this variation. And if 21.Nxe7 I would not hesitate to sacrifice the queen ...Qxe7)<21... Rxd5! 22. QxQ RxQ and now the threat of ...e2 ... Rf2 disc. check and Bc5 and hopefully a quick mate somewhere>. I have no engine check at it but it is just to show you what I thought on a sunday afternoon:) |

| patzer2: The move 23...Bxg2+! followed by the underpromotion with 24...exf1(N)! is definitely a strong winning continuation (probably the quickest line to mate) involving a sequence of several pretty followup tactics. However, if Black plays the simple alternative 23...exf1(Q)+! (instead of 23...Bxg2+! followed by the Knight underpromotion), the winning approach looks easier to visualize (especially over the board) than the game continuation. By my analysis, best play would continue 23...exf1(Q)+! 24. Qxf1 Bxg2+ 25. Qxg2 Qd1+ 26. Kh2 Rxg2+ 27. Kxg2 Qe2+ 28. Kg3 Qxe7 with an easy win for Black. However, I don't have access to my Fritz 8 or CM 9000 computer programs today to validate, so this line may be worth checking for error. |

| patzer2: Yes! Just had Fritz 8 confirm 23...exf1(Q)+! provides a winning alternative to cook the 23...Bxg2+! (followed by the 24...exf1(N)! underpromotion to a knight) solution in the recent Sunday puzzle. In other words, Black wins simply without the complicated knight underpromotion combination. The game solution with 23...Bxg2+! (followed by the Knight underpromotion) leads to a quick mate, but is more difficult (for most players) to visualize over the board. In my opinion, the simple solution 23...exf1(Q)! puts the emphasis back on the main winning "pawn double attack" tactic 20...e2! However, I must concede that the game solution is prettier (certainly more of a crowd pleaser), leads to quicker mate and requires more tactical knowledge and a deeper visualization of the position. However, the simple 23...exf1(Q)! is no less decisive. Note: This alternative does not cook 20...e2! as the main winning solution to the Sunday puzzle. It just provides a straight forward alternative to simplify the winning followup. |
